Abstract: The present viable networking technologies have been using LTE extensively. LTE-OFDM diminishes the multipath fading effect and inter symbol interference. OFDM makes use of Cyclic Prefix (CP) for data transmitting. As a result of CP (redundant data) there is wastage of power and bandwidth. To cope up with 5th generation requirements like high speed data, Machine to Machine communication (M2M), less power consumption new technique has been implemented. In this study, one such system known as OFDM-ZT (Orthogonal Frequency Division Multiplexing-Zero Tail) is considered. This is simulated using MATLAB which shows an efficient spectrum usage. In OFDM-ZT instead of CP, a tail of zero bits is added to save power. Using MATLAB tool, the simulations are made to compare the performance of OFDM-ZT with LTE-OFDM in terms of power spectral density, CCDF which shows OFDM-ZT is better than LTE-OFDM.
